The Chipstop campaign has compiled this list of 2002-03 political donations from woodchippers.

These 2002-03 figures released by the Electoral Commission show
some interesting developments. In recent years, the union which cover
loggers have been the biggest donor to the Labor Party, but has fallen
down the ranks this year. Or has it? We don't know the full
picture yet. The CFMEU has apparently not yet submitted most of its
returns, so it's too early to say whether this union retains its
position as pre-eminent woodchipping benefactor of the Labor Party.
